ABSTRACT
In order to address the need of the poultry science community for further eggshell development al studies and to the problems of establishments circulated on eggshell disposal, the researchers developed an antacid from Cobb Broiler chicken eggshells by tablet compression. Moreover, with this development, the common problem of hyperacidity was given a tentative cure. The eggshells were transported from a hatchery in Iloilo City to the PSHS WVC Research Laboratory I and was studied. The eggshells were powdered and were tested for its percent CaCO3 An antacid tablet was made using a handheld tablet maker. Percent CaCO3 was determined by titration with EDTA. It was found out that the percent CaCO3 of the eggshell and the eggshell antacid were 27.166% and 41.11% respectively. The dissolution time of the eggshell antacid suggests that it will dissolve slowly in a simulated stomach acid. The results suggest that eggshells could be made into antacids because of its calcium carbonate content but a more efficient way of making an antacid is needed.
